Fibonacci Friday Message #1 Posted by Dave Shaffer (Arizona) on 9 June 2013, 10:31 p.m. As I was reviewing financial data from last week, I realized that last Friday (6/7/13 or 7/6/13 - depending on your continent) might be loosely called a Fibonacci day - i.e. the sum of the day and month added up to the last two digits of the year. Then, I realized the real Fibonacci day for 2013 was a month ago: 5/8/13 (or 8/5/13), but alas not a Friday, so not alliterative. These numbers are from the real Fibonacci series (and best expressed, of course, if you are using a US-style date system!). The next real Fibonacci day won't be until August 13, 2021 (with, of course, some pseudo-days like last Friday before then). After that, you have to wait until the next millennium for the next true Fibonacci day: Jan 1, 3002!

Re: Fibonacci Friday Message #2 Posted by Geir Isene on 10 June 2013, 2:56 a.m., in response to message #1 by Dave Shaffer (Arizona) The next Fibonacci day is at least 5th of August 2013 (albeit not a Friday). As a side note, in the US, PI is roughly equal to 3.41
